Any war or military conflict woud destroy the flow and heritage of culture by those artists. They may die in the war or may be handicapped with injuries. Even from this standpoint, in addition to that regarding the possible victims of ordinary people, military conflicts should be strictly banned.
Our government has done a military exercise operation by Maritime Self Defence Force in the South China Sea where territorial disputes are going on among the countries around there. Japan won't do with that at all. This military action may aggravate the tension in the area.
Troops of Japan Ground Self Defence Force are planned to be deployed in the Middle East, where Israel is still bombing Palestines. Without diplomatic intervention to lessen the conflict there, any military presence won't solve the problem.
I firmly believe we should leave the world in better situation. Less military conflict and more action toward peace. Without such efforts, this exhibition of brilliant talents in the world will be meaningless or won't exist.
